2015-11-23ssh: AEAD_AES_(128|256)_GCM and aes(128|256)[email protected] cryptoHans Nilsson
Note that the rfc5647 is ambigous so this implementation of AEAD_AES_(128|256)_GCM may or may not be compatible with others. They are note enabled by default but may be enabled by the user. See the Reference Manual, Application SSH for details of how we interpret the rfc. To be safe, use [email protected] or [email protected] instead.
2015-11-23ssh: refactor packet receptionHans Nilsson
There was an assymetric relationship between receiving a ssh-packet (decrypting-mac-decompress) and sending one. When sending, most of the work was defined in the ssh_transport module, while at reception the ssh_connection_handler was the one knowing what to do. This commit moves the reception down to the ssh_transport module where it belongs.

2015-08-03ssh: Add experimental 'diffie-hellman-group-exchange-sha256 supportHans Nilsson
DO NOT USE IN PRODUCTION!!! It is not enabled by default, but may be enabled with the option {preferred_algorithms, [{kex, ['diffie-hellman-group-exchange-sha256']}]}
2015-08-03ssh: Repair/add experimental diffie-hellman-group-exchange-sha1 supportHans Nilsson
DO NOT USE IN PRODUCTION!!! This is a bug fixing of the previously partly impelmented kex algorithm. There are more things to do, for example genrate/select better g,p pair obeying the min||n||max request. It is not enabled by default, but may be enabled with the option {preferred_algorithms, [{kex, ['diffie-hellman-group-exchange-sha1']}]}

2015-05-29ssh: Check e and f parameters in kexdhHans Nilsson
rfc 4253 says in section 8 that: "Values of 'e' or 'f' that are not in the range [1, p-1] MUST NOT be sent or accepted by either side. If this condition is violated, the key exchange fails." This commit implements the reception check.
2015-05-29ssh: Set max num algoritms in msg_kexinit negotiationHans
This is to prevent some dos-attac scenarios. The limit is hard-coded.
2015-05-26ssh: Undocumented option 'compression' replaced by 'preferred_algorithms'Hans Nilsson
The 'compression' option was used in the test cases. The new option 'preferred_algorithms' is much more powerful and can be used as a replacement.
2015-05-26ssh: New option 'preferred_algorithms'Hans Nilsson
This option enables the user to define which algorithms that are to be used as well as their precedences in the negotiation between server and client.
2015-05-08ssh: Check e and f parameters in kexdhHans Nilsson

2015-04-21ssh: added id_string option for server and clientHans Nilsson
For limiting Banner Grabbing attempts.

2014-08-28SSH: only enable ciphers/MACs when they are available in cryptoAlex Wilson
Also adjusts tests to only expect a positive outcome when crypto supports the relevant base ciphers/MACs.
2014-06-10SSH: add support for aes128-ctr and hmac-sha2-256Alex Wilson
This cipher and hmac are RECOMMENDED as per RFC4344 and RFC6668. RFC4344 notes that aes128-ctr is likely to be promoted to REQUIRED in the near future. Some distros of Linux and Illumos are already shipping with aes128-cbc and 3des-cbc disabled by default due to security concerns around chosen-plaintext attacks and other information leaks. Without this patch, OTP SSH cannot connect to these SSH servers in their default configuration.
2013-11-13ssh: Merge connection_manager and connection_handler processesIngela Anderton Andin
Also start adding dialyzer specs and removing dead code
2013-11-13ssh: Remove use of process dictionaryIngela Anderton Andin
This is step one in in making ssh process structure less complicated. As an effect I also found other simplifications/clean ups of the code that could be done.
